any suggestions on what headers i can put in my 66 coupe, original had the I6, now has 302W. Not much room? thanks
tri-y's are going to give you the least hassle and the most clearance, though they may still have issues.
I went with Hedman Elites on my 289 (same). They slid right in from under the car after engine install with no problem. Great fit. They sit low so you'll lose some ground clearance. (I've got about 3 1/2-4 inches) I've been told they look wicked from someone in front of you looking in their rearview. Nickel coated and they ran about $265 if I'm not mistaken from Jegs. BTW, my car was original I6 also.
